NITED STATES PATENT JOHN MCCLOSKEY, OF LONDON,ONTARIO, CANADA.

THRASHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No; 269,692, dated December26, 1882. application filed June 25, 1881. (No model.) Iatented inCanada April 8, 1861, No. 12,607.

To all whom it may concern Be it known that I, JOHN iWIcCLo'sKEY, asubject of the Queen of Great Britain, residing at London, in the countyof Middlesex and ProvinceofOntario,Uanada,haveinvented certain new anduseful Improvements in Thrashing-Machines, (for which I have receivedIietters Patent in Canada, No. 12,607, dated April 8, 1881;) and I dohereby declare that the following is a full, clear, and exactdescription of the same, which will enable others skilled in the art towhich it appertaius to make and use the same.

My invention relates to the mechanism for operating the straw and graindecks and shaking the shoe of the separator, which are effectedconjointly; and my improvement consists in the detailed construction andcombination of parts hereinafter more fully described, and particularlypointed out in the claim.

In the accompanying drawings, Figure 1 is a. longitudinal verticalsection of so much of a thrashing-machine as is necessary to illustratemy invention. Fig. 2 is a vertical cross-section of the same throughline in m, and Fig. 3 is a vertical cross-section through line 31g ofFig. 1.

Corresponding parts in the several figures are denoted by the sameletters of reference.

F is the frame of the machine. I is the straw-deck, one end of which issuspended by hangers or stirrup-rods M M from the top part of themachine, while the other end is provided with rigid hangers L,journaledupon the cranks h of the double-crank shaft H. The cranks h ofthe latterare connected by pitmen B B with the sides of the grain-deck J, theforwardend of which is suspended by the hangers or stirrup-rods M in thefront part of the mach ne. Upon the projecting end h of shaft H is keyedthe drive-pulley G, which has a wrist-pin, upon which is journaled apitman, O, the lower end of which is connected by a toggle-joint, T,with the bell crank N, from the other arm of which a rod, U, extends upto the shoe P, in which it is fastened. Thus it will be seen that thetwo decks and the shoe are operated conjointly and by the samemechanism, the nature of which is such as to make it strong and durable,so that it does not easily get out of order.

I claim as my improvementand desire to secure by Letters Patent of theUnited States- The combination, in a thrashing-machine, of shat't'H,havingcranks it h and h h, strawdeck I, hangers L L,journaled upon thecranks h h. grain-deck J, pitmen 13 B connecting it with cranks h h,pulley Gr, pitman O, the toggle-joint T at its lower end, bell-crank N,rod U, and shoe P, all constructed and combined to operate in the mannerand for the purpose shown and set forth.
